As the basic road-map for national carbon neutralization by 2030 and the 10th basic plan for long-term electricity supply and demand plan in Korea, the installation of renewable energy sources has been rapidly increased. However, the customer voltage has frequently deviated the allowable voltage limit (220V ± 6%) during periods with off peak load due to the large scaled installation of renewable energy sources. In order to solve these problems, this paper implements 30kW scaled VPL device, which is a virtual power line technology to improve hosting capacity of renewable energy sources instead of additional investment to power system infrastructure such as distribution substation and primary feeders and also proposes the optimal capacity for the VPL device in the secondary feeder. Furthermore, this paper performs modeling of VPL device in the secondary feeder, which is composed of battery system and operation platform, by using PSCAD/EMTDC S/W. From the simulation and test results based on the proposed VPL device in the secondary feeder, it is confirmed that it can keep the customer voltages within the allowable voltage limit, and then improve the hosting capacity of renewable energy sources efficiently without additional investment to power system infrastructure.
